Specification of Letters Patent.

Application filed March 11, 1915. Serial No. 13,577.

To all whom t may concern.'

Be it known that I, CLARENCE R. RAYNES,

a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

My invention broadly speaking has relation to an improvement in pumps of that class or type known as high pressure or test pumps, such for instance as are used in conjunction with tire engines or pumping stations.

In this class of pumps the water flows to the intake at relatively low pressure and'is delivered at high pressure so that the water may be lifted many feet to 'the point lof discharge. Such pumps are usually double acting, the water being drawn in and discharged at either stroke of the plunger or piston.

. Some attempts have been made to arrange a multiple number of copera'ting cylinders and plungers into one structure whereby vthe pumps coperate to take water from an inlet and discharge to a single outlet, but so far as I am aware these attempts have been crowned with but limited success.

By my present invention any number of pumping cylinders and plungers may be grouped into a single apparatus and operated from a single crank or driving shaft and when so grouped they may be individu ally arranged with respect to the commoninlret and outlet for the apparatus that each will be double acting and so arranged that each plunger during its stroke will occupy a position some distance ahead of the plunger next in series following and a distance behind a plungernext in series in advance. In other words should six pumps be grouped, each stroke of a plunger may be divided into three portions with the plungers of three of the pumps covering the consecutive positions simultaneously whereas the other three plungers cover the three reverse positions simultaneously.

`My present invention seeks to provide a means for coupling the series of pumps together. so that they will collectively coact as a continuous double acting pump.

. It seeks also to provide a means whereby theY pumps coact tovdraw in the water from a common intake and discharge the water funder pressure to a common outlet, the arrangement andy construction of said inlet and outlet forming an important feature of my present improvement. i

My invention further seeks to provide a double acting pump of improved construe-- tion and arrangement of partsas well as to provide certain improved details of construction which will be hereinafter described and claimed.

The nature and scope of my invention will be more fully understood from lthe following description taken'in connection with the accompanying drawings forming part hereof, in which- Figure l, is a sidel elevational view partlyv in section, illustrating a multiple double acting pump embodying main features ofnify7 invention. l

Fig. 2, is an enlarged cross sectional view of the pumpe-the section being taken on line a-'a of Fig. l. v f

Fig. 3, is a transverse sectional view, enlarged, the section being taken on line b-b of Fig. l.

Fig. i is a sectional view, enlarged, ltaken on line o-c of Fig. l, and o Figs. and-6 are enlarged sectional views taken on lines d, Z and e, e, of Fig. 1 respectively to illustrate the construction and arrangement of an inlet andan outlet of the pump.

Referring to they drawingsl l,y representsv y the pump casing which is preferably ring shaped vin contour and substantiallvbox shaped in cross section. The interiorof the'- casing l is divided by a partition-orweb 2 into two compartments 3, and i of unequal area in cross-section, the larger compartment 3 being the intake and the smaller compartment 4 the dischargecha1nber-` To permit` of this unequaldivision the partition 2 is bowed or curved as illustrated for instancev in Fig. 2 and this curvature vof the partition 2 is-more or less marked adjacent tothe inlet openings 5, 5 (see Fig. 5*) at the outlet openings 6, 6 .(see Fig. 4). and at the entrance 7 to the air kdome 8.

The casing l stands preferably in a ver- 'tical'V position and the partition 2 in those portions of the casing vbetween the pumps is vertically arranged.. l i Y The pumpcasings 9 are arranged .radially around the main casing l and lcommunicate directly therewith. In the form of apparatus illustrated there are b y preference six pumps each with a casing 9 interposed in the ring casing 1. The construction and arrangement of casing 9 is clearly illustrated in 1 and 3. The casing 9 is in the form of a. box and centrally arranged within the box is a cylinder 10 having both ends open. The casing 9 is divided longitudinally by partition 2 into intake and outlet chambers 11 and 12 each communicating with both open ends of the cylinder 10.

Concentric with the cylinder 10 and with in the intake chamber 11 is arranged a double series of inlet valves 13 and 111 preferably live in each series` one series being arranged adjacent to the outer end of cylinder 10 while the other series is arranged at the in ner end of said cylinder. A valve 13 at the top opens upwardly and a valve 14. at the bottom opens downwardly of the chamber 10.

Concentric with the cylinder 10 and within the outlet chamber 12 is arranged a double series of outlet valves 15 and 16, preferably three in each series, one series l5 being arrangedadjacent to inlet valves 12 and the other series 16 adjacent to inlet valves 13. A valve 15 at the top opens downwardly into chamber 12 whereas a valve 16 at the bottom opens upwardly into the chamber 12.

lVithin each cylinder 10 between its two open ends is arranged to reciprocate a piston 17 the stem or rod 18 of which traverses a packing or gland 19 formed on the interior face of casing 9. The stem or rod 18 is connected at its free or inner end with a yoke or strap 18 carried by the two slide bars 2O each carrying a. slide 21 said slides arranged respectively to reciprocate in a guide way 22 found on either side of the casing 9. Each slide 21 is pivotally connected to one end of a link 23 Aor as will be hereinafter more fully explained to one end of an arm 24. The links 23 on one side of the casing 9 are each pivotally connected at their other end to a substantially ring shaped frame 26, and the links on the opposite side of casing 9 are pivotally connected to a correspondingly shaped frame 26. The two arms 24 for one of the pumps in series are formed integral with or rigidly connected to the frame 26.

Each frame 26 is diametrically divided into two straplike sections arranged when assembled and bolted together, to surround the crank pin 27 of a crank shaft 28 and to travel loosely' thereon.

The casing 1 with interposed pump casings 9 is substantially wheel shaped and when in preferred position is supported vertically by any preferred form of frame work. In the drawings a portion of the supporting frame and its connection with the casings 1 and casing 9 is indicated in cross section at 29.

The operation of an individual pump is as follows-As the crank shaft 28 revolves, the crank pin 27 through the two rings 26 will operate through say the rigid arms 24C the slides 21. causing said slides to ride up and down in the guide ways 22. The yoke carried by the slide bars 2O will thus be drawn toward or away from the shaft 28 and the piston rod 18 and piston 17 will be reciprocated in the pump cylinder 10. 0n the down stroke of piston 17 the upper valve 13 opens to permit of a flow of water from intake chamber 11 to the cylinder above the piston head 1 7. it the same time water forced from the bottom of cylinder 10 will open the lower valve 16 of the discharge chamber 12 and will close valve 14C at the bottom of chamber 11 and valve 15 at the top of the discharge chamber 12. On the reverse stroke of piston 17, lower valve 14e and upper valve 15 are opened whereas upper valve 13 and lower valve 16 are closed. 1n this manner water is drawn from the intake 11 and forced into outlet 12 during both strokes of the piston 17, and a feeding of the water to the pump and a discharge to the outlet takes place at relatively short intervals of time.

To render the feed and discharge of the water continuous and remove periodicity in the operation of the apparatus, the chain or cycle of pumps each communicating directly with a common intake and a common discharge chamber is provided. In this chain of pumps the various pistons reciprocate synchronously in pairs, that is to say the inner side of any given piston begins and completes its stroke in step with the outer side of the piston just opposite. Hence the pumps are arranged so that a plurality of pumps divide the period of time during one stroke and a second plurality of pumps divide the period of time during the other stroke.

Thus, referring to Fig. 1, the pump at the bottom of the wheel which is shown in section may be taken as the master puinpof the structure and this pump is the one connected by rigid arms 24 to the ring frames 26 on the crank shaft. The remainder of the pumps are so connected with the frames 26 by means of the pivoted links 23 that the pistons in these pumps occupy a position in their' respective cylinders varying from the master pump and from each other. If now as illustrated the piston in the master pump has completed its down stroke, the piston of the next pump looking to the left and upward will have completed but two thirds of its down stroke, whereas the piston of the next pump above has completed but one third of its stroke. The next piston of the pump which is diametrically opposite the master pump has just completed its up stroke and the next succeeding pistons have respectively completed but two thirds and one third of their up strokes. In this manner the water in the intake is sucked into the pumps in an uninterrupted stream and is forced from the discharge chamber to and through the air dome and out of the outlet from the pump in a constant stream in which a periodic or pulsating movement is scarcely observable. I do not Wish to confine myself to the precise form of intake and discharge chambers, nor to the precise construction and arrangement of the various parts shown in the drawings, since all of these may be varied without materially departing from the spirit of my invention. With respect to the means for operating the pumps in series I believe the mechanical movement shown and described to be new and that the same may be readily adapted for use in machines or apparatus other than pumping machinery or apparatus and still embody my invention.

Having thus described the nature and objects of my invention what I claim as new and desire to secure by Letters IatentA is- In a pumping apparatus a crank shaft, a series of pump chambers radially disposed around the crank shaft, a series of piston rods reciprocating in said cylinders, a series of yokes each arranged to operate a piston rod in series, slides carrying each yoke, guide ways on the exterior of the pump chambers in which the slides are adapted to oscillate, two ring frames arranged on said crank shaft and a series of links connecting the periphery of each ring frame with the series of slides controlled by each ring frame.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
